T0 all wlwm z't mag; concern:

Be it known that I, EDWARD G. Gnoss, a citizen of the United States, residing at Columbus, in the county of Muscogee and State of Georgia, have invented new. and useful Improvements in Sewer-Trap Caps, of which the following is a specification."

This invention relates to improvements in sewer well caps, and the primary object of the same is to so construot the cap to permit ofthe free access of water therein from the gutters and preventing the escaping of noxious vap0rs fising from the water 001- lected within the sewer well or trap.

A further object of the invention is the rovision of a, trough having detachable connection with the sewer cap, and serving as a means for permitting of the inlet of the water within the sewer well, and preventing overflowing of the sewer wells or traps which frequently occurs in cases 0f heavy min.

A st' further object of the-invention is the rovision of a gravit closing door for the inlet of the trough 01 preventing the escapement throu'gh the grating of the trough of noxious vapors or gases rising fr:}1}n the water colleeted within the sewer W v With the above and other objects in view, the invention consists in the novel features details of construction and combination 0% arts which will hereinafter be m0re fully set forbh, illustrated in the aocompanying drawing and pointed. out in the appended claims.

Figure 1 is a perspective view of a sewer p; M

Fig. 2 is an end elevation;

Fi 3 is a detail section clearly illustrating e manner of connection 0f the trough with the sewer cap.

R=Jferring more specifically to the accompanying drawing in which 1ike characters of refrence refer 130 oorresponding parts in the several views, 5 designa.tes an angular Sewer cap which may be constructed of anysuitable material such as cast iron, brick 0r cement and embodies a flat top 6 and a depending front 7. The top 6 is provid ed Wifl'l. the usual clean-out opening 8 and it is to be understood that th1s skawer trap cap is to be placedl over the well-known sewer welle and fiush with the leve1 of the side- Walk, while the freut wall7 is embedded.

within and at a point below the street level, the purpose of which will be hereinafter fully set forth.

The front Wall 7 of 'the2sewer trap is formed wi@ah an up(;aer longitudinall disppsed opemng 9, an a. lower longitu inally d1spo sed openmg 10, the said openings 9 and l0-bemg d1spos ed in superposed relation one to tl 1e other, and arranged for the greaber gort1on of the length 0f the front Wall 7. n order to prevent the entrance of leaves, tmgs, trash or the likg;}lwithh the 0 ening 9 o:f @he cap, I providejguard 11, inc udin a ser1es of spaced rods 12. Formed integra with the front wall 7 and interiorly thereof,.

the water collected within the sewer Wall from escaping from such we1l. It is to be further understood that flehewater from t!1e streets und. gutters entering the respect1ve o enings 9 and l0.will forma the doors 17 gmn 18 t0 an open position, and be deposlted within the sewer well, not shown. The doors 17 and 18 when in closed positipn, ahnt or engage with the tapering I'ib 19', for assuring of the doors assuming a full closed osition at all times.

It frequently happens during or after a hard min that the sewer W611 overflows for the reason that the inlet of such we1l is not suflicient t0 permit of the drainage of the water frondthe streets or gutters, and 120 this end, 1 attempt 1:0 overcome this 0bjectionable feature by providing the trap with a trough 21. This trough may be. 0011- structed 0f metal, masonry, or the 1ike material, and is preferably embedded within the gutter below the street level and is 0f substantially rectangular configuration embodying end walls 22, a front Wall 23 andl a downwardly and rearwardly inclined bottom Wall 24. 'Ihe trough is closed through the medium 0f a grating 25. Formed on the fronb Wall 7 of the sewer cap at a point slightly below the t0p opening 9 and at p0ints adjacent the ends 01" t-he cap is 21 pair 0f dove-tailed projections 26, while arranged below said projection 26 is a pair 0f sockets 27, the projections 26 being adapted 120 be engaged by the Sockets 28 formed in the rear Wall 29 of the t-rough 21, while the sockets 27 receive the depending projection 30 formed on the botton1 Wall 21 of the trough 21, and as will be seen through the engagement of the trough With the projections 26 and extension 30, the trough is detachably mounted upon the front wal1 7 of the tr-a.p and over the lowermost opening 10.

In briefiy describing the operation of this invention it is to be stated that the cap is positioned over thg We1l 0f the sewer trap, the latter not being shown, while the trough is properly embedded within the gutters and below the street plane and during the action of draining cf the streets and pavements, the water Will pass between the rods 12 as well as through the grating 25 of the trough. The water passing through the bars 12 will force the door 17 t0 an open position and pass Within the sewer Wall, While y the Water deposit d within the trough 21,

within the sewer through the medium of the inclined bottom Wall 24: Will be directed through the lowermost opening 10 and. in turn Swing the door to an' open position and thence be deposited W811 as is clearly Understood. After the streets have been fully drained and the Water has stopped passing within the respective openings 9 and 10 of the' cap, the doors then c1ose by gravity through the action of their Weights and conceal the openings to the extent of preventing the noxious vapors, gases and vermin rising from the water collected within the sewer Wall from escaping from the sewer, anal further serve t-o prevent the breeding of vermin or mosquitos from rising from the water deposited in the weil.

From the foregoing description, haken in connection with the accompanying drawing,

the avantages of oonstruction and of the' method of operation will be readily apparent 130 those skilled. in the art 130 Which the invention relates, and while 1 'have escribed the principles of operation 0f the invention, together with t-he device Which 1 now consider to be the best e'mbodiment thereof, 1 desire t0 have it understood that the device shown is merely illustrative, am. that such changes may' be made when dey sired as are within the scope of the claims appended. thereto.

1 claim:

l. A device of the character sei: forth, a sewer trap having a front Wall provided With a pair of superposed openings, a gravity closing valve for each of said. openings, a tapering rib arranged on the inner facenf the front Wall and to opposite sides of said opening, a trough detachably counected 0n the exterior face of the .front Wall of the seWer cap and over the openings formed therein, and a grating covering said trough.

2. A device of the character set forth, a sewer cap comprising a front Wall form'ed with upper and lower openings a; gravity closing valvefor each opening, prqections on the exterior fa;ce of the front Wall, and

a t1ough having socket for receiving the' projections of the sewer cap to support the trough horizontally of the frqnt Wall and in communication with the lower opening thereof, and. a gramting 'covering said trough.

3. A dev ice of the character Set forth comprising an angular sewer trap, the vertica1 portion of Which being formed with a 'pair of openings, a pair of -sockets formed on the exterior face of the vertical Portion of the sewer cap, a gravity closing door im! each of the openings, a trough having a, depending prqection, the projection of the trough engaging in the sockets of the cap for supporting the former on the vertical ortion of the latter, und. a. grating for said trough. In testimony Whereo-f I afix my signature in presence of two witnesses.
